Black Diamond Cosmo 350-R Rechargeable Headlamp
FOR CAMPING AND OUTDOOR PURSUITS THAT REQUIRE A SIMPLE LIGHT WITH BOTH AN ALL-PURPOSE BEAM AND NIGHT VISION
The rechargeable version of Black Diamond's Cosmo 350, the Cosmo 350 R features 350 lumens of power housed in a super compact, watertight body, making it perfect for evening walks and overnighters in the woods. The Cosmo's new compact body is more ergonomic with a lower profile for improved balance, and the updated user interface includes a second switch for easy lens selection. Powered by our BD 1500 Li-ion battery that’s charged by a micro USB, the Cosmo 350 R also features a sustainably made elastic headband with recycled textiles. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life. And thanks to its watertight construction, the Cosmo keeps lighting the way whether you're forced to bike home in the rain, or you're hiking back to camp in an unexpected downpour.

WHAT WE THINK
We’ve been using the Black Diamond Cosmo 350-R Rechargeable Headlamp on our recent hikes, and honestly, we’re really impressed with how well it performs.
With 350 lumens, it’s bright enough to light the way but not overly intense for close-up tasks. The rechargeable battery is a game-changer—it saves us from worrying about spare batteries and is a much more eco-friendly option for longer trips. We also really appreciate how comfortable it is to wear for hours, with a secure fit that stays in place, even when we’re on the move.
The various settings, including the red light mode for preserving night vision, have been super useful. For us, it’s the perfect balance of brightness, comfort, and convenience. It’s become our go-to headlamp for everything from evening hikes to early morning starts. -
